The music in this game was composed for the Tandy 3-voice, which produced more advanced sound than the default PC speaker (beeper) found in most computers running DOS. To emulate this in DOSBox, set tandy=true under [speaker] in the configuration file. To emulate this in ScummVM, overwrite the global audio settings and set Music Device to IBM PCjr under the audio tab in the individual game options for Maniac Mansion.
